uAgents is a modular JavaScript framework that empowers developers to build autonomous, decentralized AI agents which can discover peers, exchange messages, collaborate on tasks, and adapt through learning. Agents communicate over libp2p-based gossip protocols, register capabilities via on-chain registries, and negotiate service-level agreements using smart contracts. The core library handles agent lifecycle events, message routing, and extensible behaviors such as reinforcement learning and market-driven task allocation. Through customizable plugins, uAgents can integrate with Fetch.ai’s ledger, external APIs, and oracle networks, enabling agents to perform real-world actions, data acquisition, and decision-making in distributed environments without centralized orchestration.

Fetch.ai’s Autonomous Economic Agents (AEA) Framework is an open-source Python SDK and CLI toolset for creating modular, autonomous agents that can negotiate, transact, and collaborate in decentralized environments. It includes scaffolding commands to generate agent projects, templates for protocols and skills, connection modules to integrate with multiple ledgers (Ethereum, Cosmos, etc.), contract interfaces, behavior and decision‐making components, testing and simulation utilities, and a publishing mechanism to distribute agents on the Open Economic Framework network. Developers leverage its modular architecture to rapidly prototype digital workers for DeFi trading, data marketplaces, IoT coordination, and supply chain automation.

AI-Agent-Solana is a specialized framework that bridges the gap between AI-driven decision making and blockchain execution. By leveraging Solana’s high-throughput network, it enables developers to author intelligent agents in TypeScript that autonomously trigger smart contract transactions based on real-time data. The SDK includes modules for secure wallet management, on-chain data retrieval, event listeners for Solana clusters, and customizable workflows that define agent behaviors. Whether the use case involves automated liquidity management, NFT minting bots, or governance voting agents, AI-Agent-Solana orchestrates complex on-chain interactions while ensuring secure key handling and efficient parallel task processing. Its modular design and extensive documentation make it simple to extend functionality or integrate with existing decentralized applications.

Based.so offers a robust platform tailored for seamless integration with the decentralized web. It provides a streamlined interface to connect, manage, and interact with various blockchain resources. The platform supports developers, businesses, and tech enthusiasts in leveraging blockchain technologies without the need for in-depth technical expertise. With its user-friendly tools and comprehensive support, Based.so aims to democratize blockchain access, making it approachable for a wider audience.

Chainrel is a platform designed to help developers effortlessly integrate and manage blockchain events in their backend services. By utilizing Chainrel, users can listen to wallet transfers, cross-chain events, DeFi order events, or events related to their web3 projects, effectively reducing the effort needed for manual implementation. This platform is particularly beneficial in enhancing event-driven architecture, providing real-time event notifications, and ensuring seamless data flow between different blockchain networks. It's an ideal option for those looking to streamline their blockchain event management process.

Solana AI Agent Eliza is a proof-of-concept AI agent that brings the classic Eliza chatbot onto the Solana blockchain. It comprises an Anchor-based Rust smart contract that implements the Eliza dialogue patterns and a lightweight web frontend. When a user submits a message, the frontend invokes the on-chain program, which generates an Eliza-style response and writes both the prompt and reply into a Solana account. This design demonstrates how to integrate simple AI logic directly on-chain, ensuring immutable, auditable conversation logs, and provides a template for developers to build more advanced AI agents on Solana.
